一项研究论文分析了生成式AI对亚马逊自出版类型小说市场的影响。[1]研究人员检测了2023-2026年期间14,419本自出版类型小说的全文，以超过25%的AI生成文本作为判断标准，发现含有大量AI生成内容的书籍在目录中占比较大，但销售贡献相对较小。[1]然而，这一状况正在逐步改变——随着时间推移，AI书籍逐渐占据原本属于无AI文本书籍的销售份额和排名位置。[1]
数据揭示了市场的失衡。[1]在研究期间，自出版图书的数量增长了19.2倍，而季度收入仅增长8.9倍，这表明每本书的平均收入在大多数类型中出现下降。[1]AI书籍通过规模扩张而非质量优势，正在重塑这个创意内容市场的格局。[1]
A research analysis of Amazon's self-published genre fiction market between 2023 and 2026 reveals the growing impact of generative AI on the creative publishing landscape [1]. The study examined the full text of 14,419 self-published genre novels and identified those containing substantial AI-generated content, defined as exceeding 25% of the text [1]. While AI-generated books initially represented a small fraction of sales despite their growing presence in the catalog, they have gradually captured market share and ranking positions over time [1].
The data demonstrates a stark divergence between volume and revenue growth in the market [1]. During this period, the number of books increased by a factor of 19.2, while quarterly income rose by only 8.9 times [1]. This expansion has diluted average earnings per book across most genres, as AI-generated works achieve market penetration through scale rather than quality [1]. The research, submitted in July 2026, documents how generative AI is reshaping the competitive dynamics of creative publishing on a major platform through volume-driven displacement of traditionally authored works [1].
